Virtex-6 FPGA - How do I target -2E speed grade for LX550T, LX760T, SX475T, and HX380T devices in the ISE design tools?


The Virtex-6 FPGA family hasfour devices which support -2E speed grade: 6VLX550T, 6VLX760T, 6VSX475T, and6VHX380T. The ISEdesigntools do not show -2E speed grade as a selection for any of these devices.


To target -2E speed grade,select-2 speed grade in ISE Design Suite. The -2 speed file works forcommercial (C), industrial (I),and the new industrial (E) temperature grades.
